Abstract

The invention belongs to the technical field of grassland degeneration restoration, and discloses a restoration method of grassland patch sandy land, which includes: collecting grassland image data, performing preprocessing and feature extraction, and obtaining the range of grassland patch sandy land; Node static technical information of soil conditions; based on the grassland patch sandy land range and node static technical information, dig trenches at the sandy land boundary and plant poplar trees at the bottom of the ditch; cover the inner surface of the patch sandy land with pre-plants Fiber nets to build biological fences; plow the patchy sandy land of the grassland, and apply soil repair and water-retaining agents; plow the soil, create ridges, break the hardening and leveling of the ridge surface; sow pasture seeds in the leveled sandy land , covering soil, watering, and field management; replanting based on the grassland conditions in the following year until the grassland recovers. The invention can improve the soil physical structure of the patchy sandy land, increase the fertility of the patchy sandy land, resist the harsh arid environment of the grassland, and promote the growth of grass.

Description

technical field [0001] The invention belongs to the technical field of grassland degradation and restoration, and in particular relates to a restoration method for grassland patch sandy land. Background technique [0002] At present, my country's grassland area is about 400 million hectares, accounting for 40.7% of the country's land area. It is the largest terrestrial ecosystem and the most important green ecological barrier, and it is also an important support for the basic production and living means of farmers and herdsmen. However, due to man-made reasons such as unreasonable grazing systems, blind reclamation, and indiscriminate logging, as well as natural disasters such as seasonal droughts, pests and diseases caused by climate change, about 90% of the available grasslands have been degraded to varying degrees. The main manifestations of grassland degradation are the reduction of grassland vegetation coverage, the change of plant community structure, the reduction of ...
